Abstract

1394692 Laminates MITSUI TOATSU CHEMICALS Inc 17 Oct 1972 [22 Oct 1971] 47807/72 Heading B5N A laminated sheet material is produced by extruding a thermoplastic resin to form a flat sheet 4, passing it at a controlled temperature through a gap between a pair of rolls 8, 9 provided with temperature control means and having corrugated surfaces to form a corrugated sheet 4a of which the corrugations extend parallel to the drawing direction of the sheet into the roll gap, depositing on the corrugated sheet a flat sheet 5 of extruded thermoplastic resin while the corrugated sheet is retained on the downstream roll 9, adhering the sheets together by blowing air or other fluid thereon from blowing means 11 so that they are pressed together and then either cooling the opposite faces of the resultant laminate separately or directing the resultant laminate to a roll 10 provided with temperature control means, depositing on the corrugated sheet 4a a flat sheet 6 of extruded thermoplastic resin, adhering the sheets together by blowing air or other fluid thereon from blowing means 12 so that they are pressed together and cooling the opposite faces of the resultant laminate separately by means of 13 and 13<SP>1</SP>. Touch rolls 7, 7<SP>1</SP> may be provided with a mechanism for varying the contact angle of sheet 4 and with cooling means. Corrugated rolls 8 and 9 may be provided with a speed control means so that the roll 9 rotates at a peripheral speed 1-20% greater than that of roll 8, and roll 10 may rotate at the same peripheral speed as roll 9. Pinch rolls 15 and 15<SP>1</SP> may have a peripheral speed 1-10% greater than that of roll 10. The sheets may be of crystalline propylene based polymer. Cooling means 13, 13<SP>1</SP> may each be divided into a plurality of segments and provided with independent temperature-adjusting means.
